Futuristic batteries ( Physics)

What prompt me to do this because the last couple of weeks, I was either making batteries or building a complicated series of circuit to finish my semester worth of work in science.

Well 100 years ago ,Thomas Edison and Henry ford make a bet how the would cars evolve in the future . Thomas Edison that the electric car and he invented and pioneer inventions of batteries but Ford disagree and said it was gonna be fossil fuel or gasoline.

And everybody know who won . But now who will win in the future ??

Gasoline, in some sense is concentrated sunlight time probably at the dinosaurs age ( process that takes millions of years) . Per kilogram the how many joules per gasoline is much larger than the energy content of a battery .

So it takes a large battery to compensate the energy contain in gasoline. Which is quite efficient even though it pollute like hell . Thats why there should be a new generation of batteries.
Some scientist believe nano-battery may be the future . It turns out if you wanna store energy. You can store energy in parallel plates call capacitors. Plates can be make extremely thin as thin as molecules. So in principal you may be aloud to store enormous amount of energy in carbon nano fibers and plates call graphin .
Thats why they believe nano technology might be able to make super charge battery. But not yet because there's much to investigate and learn about nano technology. So right now, though luck for gasoline is still the efficient source of fuel ( but hard for the environment)
